The main purpose of this thesis is to develop a small size, low cost, and efficient maximum power point (MPP) tracker for individual photovoltaic (PV) panels to charge the storage devices in a standalone system. The proposed topology presented is a reversed buck boost converter enabling parallel power processing (PPP) with a power switch referenced to the common return. Small signal analysis of the proposed charging system is carried out to show the response of the system for any change in the duty ratio. The simulation and experimental results confirmed the validity of the model and the high efficiency system operation with MPP tracking.
The use of the PPP with the split loads is also presented along with the simulation results. The results demonstrated an improvement in the size, efficiency and step down duty ratio of the used converter.
A PPP based fast battery charger topology for electric vehicles is also presented as an additional application for the topology in this thesis. The proposed topology has high system efficiency as well as reduced voltage stress on decoupling capacitor. The enhancements of the proposed charging topology are evaluated and the results are demonstrated through an example design.
